Application filed May 12, 1925.

' improvements in a vibrator.

One object of this invention is to provide an implement of the. character described specially designed for attachment to a dental hand piece and provided for the purpose of massaging and exercising the gums and other parts of the mouth, in the treatment of yorrhea and other mouth diseases.

other object of the invention is to provide a vibrator which may be operatively connected with the chuck of the conventional dental drilling appliance, for operation.

With the above and other objects in view this invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a plan view of the vibrator. I

Figure 2 shows a side view thereof, applied-to a dental handpiece.

Figure 3 shows a sectional view thereof taken on the line 33 of Figure 2, and

Figure 4 shows a sectional view thereof, taken on the line 4.4 of Figure 2.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 designates the conventional dental hand iece, which contains the usual chuck (not s own) for receiving the dental drill.

frame, preferably formed of rather stifi' wire. A clamp member 3 is provided, which is of a contour to fit around one side of the hand piece, and one end of which has flexible clamp jaws 4, 4 which clamp around said hand piece. The other endof this'clamp member is upturned, forming a thumb rest 5.

The-closed end of the frame is upturned and works in a transverse bearing 6 in the clamp member 4. The arms of the frame are connected, and held comparatively rigid, by an arcuate bridge 7, thus preventing the relative twisting of said arms, and holding The "numeral 2 designates a U-shaped Serial No. 29,674.

them in alignment while the vibrator is in use. Beyond this bridge the arms are bent toward each other or converge, and their free. ends are parallel. The parallel portions are also connected'by a bridge 8 hav ing a central bearing 9.

The numeral 10 designates an oblong friction, or massaging member, preferably formed of rubber, or similar material, and which is fastened to the-free ends of said arms of the frame. These arms are preferably inserted endwise into said friction member, but do not extend its full length, so as to permit its free end to yield, or bend, and thus more easily follow the contour of the mouth, in use and not to be too severe in application to the tender parts. One side of the member 10 has a plurality of projections or teeth 11, and on its otherside, at

its free end, it is formed with a vacuum cup 12. The teeth are for friction, or massaging purposes, while the application of the vacuum cup promotes circulation.

A shaft 13 is provided. One end of this shaft is adapted to be inserted in the hand piece chuck by means of which the shaft is rotated, and the other end of the shaft is eccentric or offset and works in the"bearm i ing -9. i As the shaft is rotated it is obvious that a vibratory movement will be imparted to the member 10, and when applied to the parts to be treated will massage the same a ieldable free portion at the outer end of of the frame arms are inserted so as to leave a yieldable portion at the outer end of said massaging member, a vacuum cup on one side of said member and tooth like projections on the other side of said member.

3. A Vibrator including a clamp formed with jaws, a U-shaped frame Whose closed end has a bearing in said clamp, a pair of bridges connecting the arms of the frame, one ofsaid bridges having a bearing, a shaft having an eccentric Wrist which Works in said bearing, a resilient massaging member into which the free ends of the arms are in- 10 serted only part of the way leaving the outer end of said member yieldable, a vacuum cup on one side of said member and projecting teeth on the other side thereot.

In testimony whereof I have signed my 15 name to this specification.
